A florist has 30 carnations and 42 roses. He wants to put the flowers in vases so that each vase has the same number of flowers
Nesterboy [21]

Note that

  • 30=2·3·5;
  • 42=2·3·7.

Find the grearest common factor GCF(30,42). You can see that numbers 30 and 42 have common factors 2 and 3, then

GCF(30,42)=2\cdot 3=6.

This gives that the greatest number of identical vases florist can fill is 6. Each vase will contain

  • 30:6=5 carnations;
  • 42:6=7 roses.

Therefore, in each vase will be 12 flowers (5 carnations and 7 roses).

Need help with this math question.
anastassius [24]
<h3>Answer:</h3>

B. 1 : 26

Step-by-step explanation:

Let the volume of large cone, the volume of water and the volume of air in the cone be V,

Vw and Va.

Since the cone of water is similar to the large cone and we know its height is x3 smaller,

Vw = (1/3)^3 * V = V/27

Also, Va = V - Vw

= V - V/27 = 26/27 V

Hence, Vw : Va

1 : 26

The equation y 4.9t 2 3.5t 2.4 relates the height y in meters to the elapsed time t in seconds for a ball thrown downward at 3.5
tamaranim1 [39]

Answer:

t \approx 0.43\,s

Step-by-step explanation:

The vertical displacement function is y(t) = -4.9\cdot t^{2}-3.5\cdot t + 2.4, where y(t) is measured in meters and t in seconds. Ball hits the ground when y(t) = 0. That is:

-4.9\cdot t^{2}-3.5\cdot t + 2.4 = 0

Whose roots can be found by using the General Formula for Second-Order Polynomials:

t_{1,2} = \frac{3.5\pm \sqrt{(-3.5)^{2}-4\cdot (-4.9)\cdot (2.4)} }{2\cdot (-4.9)}

Solutions of this polynomial are:

t_{1} \approx 0.43\,s,t_{2} \approx -1.14\,s

Only the first root is physically consistent.
